Answer:
4
Step-by-step explanation:
The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100
They have 4 in common
100 = 2*2*5*5
84 = 2*2*3*4
the greatest common factor is a prime number whit most appearance in both numbers:
in this case the prime number is 2 and it is repeated twice in both numbers, hence 2*2 = 4
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 30 = x/8
8 sin 30 =x
8 (1/2) = x
Answer: 5 x 2 − 10 x = 5 x ( x − 2 )
No.
3/4 is not less than 2/10.
3/4 = 15/20
2/10 = 4/20
15/20 > 4/20
